[0027] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] A specific embodiment of the present utility model provides an automatic cloth pulling machine, which mainly includes a machine head and a pulling hand in combination with the attached Figure 1 as shown, and mainly includes a machine head and a pulling hand.

[0029] Wherein, the machine head is arranged at one end of the bench 1 for loading materials. The cloth is clamped on the machine head for the pulling hand to pull the cloth, and the cloth is clamped again after the cutting is completed.

[0030] The pulling hand is movably arranged on the bench 1. The pulling hand is used to reciprocate on the bench 1 and complete the cloth pulling operation during the movement. When the pulling hand approaches the machine head, it clamps the cloth on the machine head. When the pulling hand moves away from the machine head, it stretches the cloth so that the cloth is laid flat on the bench 1.

[0031] The gantry 1 pointed out in this application has a general platen 2. Such a gantry 1 is also a general platen. A gantry with a general platen 2 on the market can be directly adopted. Both ends of the handle are slidably arranged on the general platen 2 through a sliding limit device. The sliding limit device includes a sliding part 3 and a first limit part 4. The sliding part 3 abuts against the upper plate surface of the general platen 2, and the first limit part 4 abuts against the side wall of the general platen 2. The sliding part 3 plays a role in supporting the handle and slidingly connecting with the general platen 2, while the first limit part 4 restricts the movement of the handle. The sliding limit device is arranged at both ends of the handle, and the two first limit parts 4 of the sliding limit devices at both ends of the handle can limit the handle from both sides of the general platen 2. A driving part 5 and a transmission part connected to the driving part 5 are arranged at the bottom of the gantry 1. The driving part 5 is used to drive the transmission part to act. The transmission part is arranged along the length direction of the gantry 1. The sliding limit device is connected to the transmission part. In this way, under the driving action of the driving part 5, the transmission part can be driven to act, and indirectly the transmission part can drive the sliding limit device and the machine head to act.

[0032] Using such an automatic cloth pulling machine does not require separately designing a special gantry to cooperate with the handle. This application only needs to be set on the general platen 2 to be used. Thereby, the applicable range of the automatic cloth pulling machine is increased, the machine cost is reduced, and the general platen 2 can be reasonably utilized to avoid waste of resources.

[0033] In a specific embodiment of the present application, the machine head includes a first mounting bracket 6, a pressing cylinder 7, a pressing plate 8, a pressing block 9, a reciprocating driving assembly 10, and a cutting knife 11. The bottom of the first mounting bracket 6 is connected to the table frame 1. The first mounting bracket 6 includes two vertical rods vertically connected to the table frame 1 and a cross bar parallelly connected between the two vertical rods. The pressing cylinder 7 is arranged on the first mounting bracket 6, that is, the pressing cylinder 7 can be arranged on the upper cross bar. The movable end of the pressing cylinder 7 is provided with the pressing plate 8, and the movable end of the pressing cylinder 7 faces downward. The pressing block 9 is located below the pressing cylinder 7, and the pressing plate 8 can abut against the pressing block 9. The cloth can be clamped through the pressing action of the pressing plate 8 and the pressing block 9. The reciprocating driving assembly 10 is arranged on the first mounting bracket 6, and the driving direction of the reciprocating driving assembly 10 is along the width direction of the table frame 1. The reciprocating driving assembly 10 can be arranged on the two vertical rods and the upper cross bar. The reciprocating driving assembly 10 can include a motor, a synchronous pulley, and a synchronous belt. The output end of the motor is provided with a driving pulley, and the driving pulley and the synchronous pulley are respectively located on the two vertical rods, and the synchronous belt is sleeved on the driving pulley and the synchronous pulley. The cutting knife 11 is arranged on the reciprocating driving assembly 10. The cutting knife 11 can be arranged on the synchronous belt, and the blade part of the cutting knife 11 is arranged close to the pressing block 9 for cutting the cloth. The cutting knife 11 can also be slidably connected to the first mounting bracket 6 through a slide rail to ensure the stability of the cutting knife 11. A plurality of notches 12 are evenly distributed at one end of the pressing plate 8 and the pressing block 9 facing the handle. When the pressing plate 8 and the pressing block 9 press the cloth, there is cloth at the position of the notches 12, which is convenient for the handle to clamp the cloth.

[0034] In a specific embodiment of the present application, the handle includes a second mounting bracket 13 and a pneumatic gripper 14. Both ends of the second mounting bracket 13 are slidably connected to the general table board 2 through sliding limit devices. The pneumatic grippers 14 are multiple and are evenly arranged along the length direction of the second mounting bracket 13. The pneumatic grippers 14 can extend into the notches 12 to clamp the cloth. Specifically, the number of the pneumatic grippers 14 can be the same as the number of the notches 12 and are arranged in one-to-one correspondence. In this way, the cloth can be integrally clamped from the width of the cloth by the pneumatic grippers 14 extending into the notches 12.

[0035] In some embodiments, the sliding limit device abuts against the metal edging on both sides of the general table board 2. It should be noted that in the prior art, for the general table board 2 used in the commonly used manual cutting table frame, there is usually metal edging on both sides of the general table board 2. When the handle of the present application is arranged on the general table board 2, the sliding limit device acts on the metal edging. The metal edging has stronger structural strength and wear resistance, so that the automatic cloth pulling machine of the present application can be combined with the general table board 2 and can be used for a longer time.

[0036] In some embodiments, the sliding limiting device further includes a second limiting portion 15, and the second limiting portion 15 abuts against the lower plate surface of the universal platen 2. In this way, the sliding portion 3, the first limiting portion 4, and the second limiting portion 15 can abut against the universal platen 2 from above, below, and the side, and in the direction away from the side wall of the universal platen 2, the first limiting portions 4 at both ends of the handle are limited to each other, restricting the movement of the handle. In this way, the handle can be restricted on the universal platen 2 and can only move along the moving direction.

[0037] In some embodiments, the sliding portion 3, the first limiting portion 4, and the second limiting portion 15 are all rollers, and the rolling surfaces of the rollers abut against the universal platen 2. The roller method can minimize the frictional resistance between the sliding limiting device and the universal platen 2, so that the handle can slide smoothly on the universal platen 2, reduce the burden on the motor, and lower the energy consumption.

[0038] In some embodiments, a connecting frame 16 is provided at the bottom of the sliding limiting device, and the connecting frame 16 is connected to the transmission portion. The connecting frame 16 can be a connecting plate. By connecting the connecting frame 16 to the transmission portion, it is ensured that the transmission portion can drive the handle to move.

[0039] In some embodiments, in combination with the attached Figure 1 and the attached Figure 4 , wherein the transmission portion includes a transmission rod 17, a driving wheel 18, a driven wheel 19, and a transmission body 20. The driving portion 5 is a motor for providing driving force. The middle of the transmission rod 17 is connected to the output shaft of the motor. Specifically, a fixed pulley is provided in the middle of the transmission rod 17, and the fixed pulley is connected to the driving pulley on the motor by a belt. Driving wheels 18 are provided at both ends of the transmission rod 17. On both sides of one end of the two driving wheels 18 close to the universal platen 2, there are two driven wheels 19 and they are provided on both sides of the other end close to the universal platen 2. The transmission body 20 is sleeved on the driving wheel 18 and the driven wheel 19 on the same side of the universal platen 2. In this way, the transmission body 20 can be provided at both sides of the universal platen 2 and is connected to two sliding limiting devices respectively from both sides, thereby ensuring the stability of the connection of the handle. The transmission body 20 is connected to the sliding limiting device. The transmission body 20 is a transmission chain or a transmission belt, and the corresponding driving wheel 18 and driven wheel 19 can also be gears or pulleys.

[0040] In some embodiments, it further includes a fixed connection bracket 21, a movable connection bracket 22, and an adjusting member 23. The fixed connection bracket 21 is disposed close to the driven wheel 19. The fixed connection bracket 21 is fixedly arranged on the bench 1 and is arranged at one end away from the machine head. The movable connection bracket 22 is slidably arranged on the fixed connection bracket 21. One end of the adjusting member 23 is connected to the fixed connection bracket 21, and the other end is connected to the movable connection bracket 22. By means of the adjusting member 23, the position of the movable connection bracket 22 on the fixed connection bracket 21 can be adjusted. The sliding direction of the movable connection bracket 22 and the adjusting direction of the adjusting member 23 are both in the same direction as the length direction of the transmission body 20. The driven wheel 19 is arranged on the movable connection bracket 22. In this way, the position of the driven wheel 19 can be adjusted. Since the adjusting direction is in the length direction of the transmission body 20, the tightness of the transmission body 20 can be adjusted in this way.

[0041] In some embodiments, a first U-shaped groove 24 is provided in the direction of the fixed connection bracket 21 facing the transmission body 20, that is, the fixed connection bracket 21 can be designed as a U-shaped frame structure. Bar-shaped holes 25 are provided on two opposite side walls of the fixed connection bracket 21. Both sides of the movable connection bracket 22 are slidably arranged in the bar-shaped holes 25 through connecting columns. In this way, the movable connection bracket 22 can move along the length direction of the bar-shaped holes 25. A second U-shaped groove 26 is provided in the direction of the movable connection bracket 22 facing the transmission body 20, that is, the movable connection bracket 22 is also designed as a U-shaped frame structure.
